ISOLUTE® QuEChERS (pronounced 'catchers') stands for Quick, Easy, Cheap, Effective, Rugged and Safe.
The technique is designed to be simple and involve a minimal number of steps, but still allow for effective clean-up of complex samples. The QuEChERS technique involves two stages:
i) a crude extraction and partitioning step using organic solvent and salt solution followed by
ii) further extraction and clean-up using dispersive SPE.
Using ISOLUTE® QuEChERS tubes, analysts no longer need to weigh individual components, which makes the method quicker and more reliable.
- No need to weigh individual components – faster and more consistent
- Include extraction tubes for the initial extraction and partitioning of analytes from homogenized food samples
- Include clean up tubes for the dispersive solid phase extraction
- Unique shipping and storage rack
- Solvent resistant paper labels aid hassle free sample identification
ISOLUTE® QuEChERS products include extraction tubes for the initial extraction and partitioning of analytes from homogenised food samples, and clean-up tubes for the dispersive SPE. All ISOLUTE® QuEChERS products come packed in a rack for ease of storage and use on the bench. Solvent resistant paper labels aid hassle free sample identification.
AOAC 2007.1 and EN15662 methodologies
Biotage supplies pre-weighed extraction and clean-up tubes that conform with AOAC and EU published methods, including those for waxed and highly pigmented fruit and vegetable samples.
Biotage’s strict quality control during the manufacturing process ensures consistent performance in an already well defined methodology.
The 15 mL extraction and clean-up tubes contain sufficient sorbent to process samples according to prescribed AOAC1,2 and EN3 methodologies and allow for immediate sample mixing and transfer to larger 50mL sample tubes. All QuEChERS products are shipped in a cardboard rack for ease of use and contain full instructions following the EN and AOAC methodologies.
